There is no need to do this at the top of the handler, move this

Currently, there are some links that we access with **HTTP**, it is
redirected to **HTTPS** automatically. So this commit aims to
replace **http://...** by **https://...** for security.

Reload didn't take proper care to protect the fields from use in
different goroutines. Add a mutex and add helpers for usage and
interval.

The [ADDRESS] field in the metrics plugin is not explained in a manner
that makes it immediately obvious, that what we are talking about here
is a listening address.

* plugin/hosts provide more configuration flexibility
This patch adds few features to the host plugin
* no-reverse (both as first argument on the plugin line and inline)
disable the automatic generation of reserve entries for hosts
* ttl <duration> (inline only atm)
allows to change the default ttl (default 5 minutes)
* reload <duration> (inline only atm)
allows to change the reloading interval (default 5s)
* plugin/hosts remove superfluous parameters to parse

* pkg/replace: make it more efficient.
Remove the map that is allocated on every write and make it more static,
but just defining a function that gets called for a label and returns
its value.
Remove the interface definition and just implement what is needed in our
case. Add benchmark test for replace as well.
Extend metadata test to test multiple values (pretty sure this didn't
work, but there wasn't a test for it, so can't be sure).
Update all callers to use it - concurrent use should be fine as we pass
everything by value.
Benchmarks in replacer:
new: BenchmarkReplacer-4 300000 4717 ns/op 240 B/op 8 allocs/op
old: BenchmarkReplacer-4 300000 4368 ns/op 384 B/op 11 allocs/op
Added benchmark function to the old code to test it.
~~~
func BenchmarkReplacer(b *testing.B) {
w := dnstest.NewRecorder(&test.ResponseWriter{})
r := new(dns.Msg)
r.SetQuestion("example.org.", dns.TypeHINFO)
r.MsgHdr.AuthenticatedData = true
b.ResetTimer()
b.ReportAllocs()
repl := New(context.TODO(), r, w, "")
for i := 0; i < b.N; i++ {
repl.Replace("{type} {name} {size}")
}
}
~~~
New code contains (of course a different one). The amount of ops is
more, which might be good to look at some more. For all the allocations
is seems it was quite performant.
This looks to be 50% faster, and there is less allocations in log
plugin:
old: BenchmarkLogged-4 20000 70526 ns/op
new: BenchmarkLogged-4 30000 57558 ns/op

This was added, but didn't see any use. For a large, complex chunk of
code we should have some users of it.

When a query, different from a TXT lookup is performed, all services
with a missing `Host` field should be filtered out, as these otherwize
cause a line in the answer section with a single dot (`.`) as the
result. This behavior manifests for example when a TXT record is present
on a domain, eg. an A or SRV lookup is performed on said domain.
If there are no services containing a `Host` field, a `NODATA` response
should be given. If there are other Services, these alone should be
returned for the query.
Filter any service that has an empty Host field from all lookup types
other than TXT to solve this issue. At the same time the check for empty
`Text` fields in TXT queries are also moved to the same check in the
etcd ServiceBackend.

There are string ttls at commands at README.md.
But because `TTL` of `Service` is uint32, commands at README is wrong.
e.g.) `etcdctl put /skydns/local/skydns/x1 '{"host":"1.1.1.1","ttl":"60"}'`.
|
|
The `b` struct is just copying all the fields into a new one, to
check if it already existed in a set. This isn't needed as all the
fields are identical, and a small rearrangement of the code solves the
same problem without the copy.

This fix deprecates endpoints for out-of-cluster k8s api,
The Corefile still takes multiple endpoints though only
the first one is used. A warning is shown if there are
multiple endpoints.

* Default to upstream to self
This is a backwards incompatible change.
This is a massive (cleanup) PR where we default to resolving external
names by the coredns process itself, instead of directly forwarding them
to some upstream.
This ignores any arguments `upstream` may have had and makes it depend
on proxy/forward configuration in the Corefile. This allows resolved
upstream names to be cached and we have better healthchecking of the
upstreams. It also means there is only one way to resolve names, by
either using the proxy or forward plugin.
The proxy/forward lookup.go functions have been removed. This also
lessen the dependency on proxy, meaning deprecating proxy will become
easier. Some tests have been removed as well, or moved to the top-level
test directory as they now require a full coredns process instead of
just the plugin.
For the etcd plugin, the entire StubZone resolving is *dropped*! This
was a hacky (but working) solution to say the least. If someone cares
deeply it can be brought back (maybe)?
The pkg/upstream is now very small and almost does nothing. Also the
New() function was changed to return a pointer to upstream.Upstream. It
also returns only one parameter, so any stragglers using it will
encounter a compile error.
All documentation has been adapted. This affected the following plugins:
* etcd
* file
* auto
* secondary
* federation
* template
* route53
A followup PR will make any upstream directives with arguments an error,
right now they are ignored.

This fix will error out when multiple https endpoints are specified,
as additional work is needed to support beyond http.
